At MYB 41 activates ectopic suberin synthesis and assembly in multiple plant species and cell types

Plant Journal, 2014
Suberin is a lipid and phenolic cell wall heteropolymer found in the roots and other organs of all vascular plants. Suberin plays a critical role in plant water relations and in protecting plants from biotic and abiotic stresses.

Symplasmic and transmembrane zinc transport is modulated by cadmium in the Cd/Zn hyperaccumulator Sedum alfredii

Ecotoxicology and Environmental Safety
This study investigated the influence of Cd (25 µM) on Zn accumulation in a hyperaccumulating (HE) and a non-hyperaccumulating (NHE) ecotype of Sedum alfredii Hance at short-term supply of replete (Zn5, 5 µM) and excess (Zn400, 400 µM) Zn.

Root cell wall plasticity in iron homeostasis: an overlooked frontier in plant nutrition. [PDF]

New Phytol
Summary Iron (Fe) is an essential micronutrient for plant growth and development, yet its availability in soils is often limited or excessive, leading to widespread Fe deficiency or toxicity that constrains crop productivity. While Fe uptake, transport, and signaling pathways have been well characterized, the role of the root cell wall as a dynamic ...

Regulatory Programmes Driving Suberin Plasticity Under Aluminium Stress in Barley Roots. [PDF]

Plant Cell Environ
ABSTRACT Aluminium (Al) toxicity is a major factor limiting plant growth in acidic soils. The beneficial element silicon (Si) can mitigate some effects of Al. However, the impact of Al on suberized apoplastic barriers in roots is largely unknown while the effects of Si on suberin remain controversial.

Sclerified Cork Outperforms the Exodermis: Root Water Permeability Decreases in the Soil-To-Canopy Transition of the Aroid Vine Epipremnum aureum. [PDF]

Physiol Plant
ABSTRACT The aroid vine Epipremnum aureum undergoes changes in habitat and growth axis direction from terrestrial (plagiotropic) to canopy (orthotropic) conditions. Since aerial roots connected to the forest soil are vital for water and nutrient uptake in these vines, we hypothesize that morphophysiological acclimation occurs, enabling root survival ...

Study on Effects of salt stress on the Suberin Lamella of grapevine roots

BIO Web of Conferences, 2023
Grape is one of the oldest tree species in the world which have a relatively high tolerance to salt stress. The function of Suberin Lamella is to control the transport of water and ions, which has a positive effect on salt tolerance. However, whether the suberin lamella of grape root is related to its salt-tolerance has not been revealed. In this study,

AhBWR15, A Novel RLK Gene, Confers Resistance to Ralstonia solanacearum in Peanut. [PDF]

Plant Biotechnol J
ABSTRACT Bacterial wilt (BW), a severe soil‐borne disease caused by Ralstonia solanacearum, significantly impedes global peanut production. Despite its impact, the mechanisms underlying BW resistance in peanut remain unclear. Herein, we selected the highly resistant variety Nongdahua108 (H108) and the susceptible variety Nongdahua107 (H107) to develop ...

Bundle sheath suberisation is required for C4 photosynthesis in a Setaria viridis mutant

Communications Biology, 2021
Florence Danila et al. perform mutation screens on Setaria viridis and identify an ABCG transporter gene which serves as a step in the suberin synthesis pathway.

Auxin Signaling Mediated Spatial Accommodation Mechanisms During Lateral Root Development. [PDF]

Physiol Plant
ABSTRACT Spatial accommodation, the ability of plant tissues to adapt structurally during organogenesis, is important for the successful growth and emergence of new organs, such as lateral roots, through overlying cell layers. This process requires precise coordination between cellular architecture and physical as well as biochemical signals.
